This reply is somewhat late, but, the WSOD on the i856 is thought to be caused by the ribbon cable breaking or tearing in the slide. If it is under warranty, contact motorola. But do it quickly, the phone only has a 90 day warranty.

I have the same problem and i have yet to figure it out. Im taking the phone to sprint for fixing or i could just call them and maybe that would solve it over the phone. will post answer with in the next 7 hours

Well what sometimes happens is your phone gets confused because when your cell phone is shut the screen doesnt go dark it is a plan white screen so what I think happend to your phone is that the sensor that is on your keypad is messed up somehow and thinks it is open when its shut.
The same thing happened to me before but my phone got wet.
